IMPROVEM ENT IN OIL-FEEDERS.

Specification forming part of' Letters Patent No. 3.031, dated April 6, 1843.

, D to its termination at D within the can. It

Be it known that I, ROBERT CORNELIUS, of should'extend across the interior of the can the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful manner of constructing an oil-can for the filling of lamps, by means of which improvement the oil will cease to ilow from the can as soon as it has attained the height to which it is desired that it shall rise' within the lamp, and

Vby which lamps maybe filled in the d ark.

fect, however, may be attained by means of a;

cork tting well into the neck, so as to close it air-tight, but the screw-cap is to be preferred as being more certain in its operation.

D D is a tube open at both ends, its outer end terminating with the opening in the spout,

and its inner end opening into the upper part of the oil-can. rIhe tube D must have an inclination downward from the upper side ofthe spout to the interior of the can when the latvter stands upright, and the tube D D- should have its capacity enlarged, say, from the point also, nearly to the side opposite to that atwhich it enters, in order that it may be kept from all danger of having its interior opening covered with oil when the can is tilted. If the tube D D is vnot larger as it proceeds toward the can than it is at its outer end, its action will not be certain.

When a lamp is tobe filled by means of this can, the end of the spout must be passed into said lamp, so as to reach that point which it is desired the oil should attain. As the oil runs from the spout, air will passinto the can through the tube D D, and this operation will continue until the oil rises so as to close the opening of said tube, and as air cannot then ROBERT CORNELIUS.
